[TRNSYS-users] "Tank in Tank" thermal storage

[Jeff Thornton]

<I have been looking among all the types for the thermal storage but I can
not say which one could model a "Tank in Tank" thermal storage. Do yo
think Tess Type 534 would be appropriate or is there another type which
best fit the "Tank in Tank" storage system?>

We're in the process of writing a tank-in-tank model but it won't be ready
for a few weeks.  In the meantime, Type 531-534 can model Tank-in-tank
systems with a few limitations.  You won't be able to account for
stratification/destratification due to conductivity as the model does not
consider this for the HX (in this case your immersed tank is just a large
HX).  You also won't be able to account for the losses from the immersed
tank to the large tank from the top and bottom surface.

Hope this helps.

Jeff
